Agile bandwidth management techniques in slotted all-optical packet switched networks

Contention avoidance in bufferless slotted optical packet switched networks with egress switch coordination

“…Loose coordination mechanisms among ingress switches in metro networks have been proposed in [17,18] as contention reduction schemes, but they only work under star topology. The work in [19] uses traffic smoothing in edge switches by rate prediction and renegotiation in slotted-OPS.…”
